42. Hysteresis is one cause of electrical power loss associated with electricity generation equipment. What phenomenon results in hysteresis?
Hysteresis loss results from heat generated as magnetic polarity reverses within a material due to an alternating magnetic field; this lagging realignment of magnetic domains causes friction and heat. Arcing, pulsating current, and excessive field current are unrelated phenomena.
